This invention, generally designated by the character reference I!) is acarcass splitting device, such as is conventionally employed in thepacking house industry. The device is suspended by a counter-weightedflexible carrying member, which is carried by a pulley disposed on araised horizontal trolley. A carcass is suspended from the trolley andis divided into two halves by a power driven saw. v

The carcass splitter l8 comprises a casing or housing :2 of anelliptical configuration. Tapped bosses I t are provided along the innersurface of the casing for accommodating conventional fasteners forsecuring a cover plate to the casing. A conventional electric motor I6is secured to the .closeld. sideof the-.casin by meansnfzan. inte ral.extensionpr shelf i.

The opposite end of the saw arm terminatesin a guide eye or member 58. A conventional saw blade 60 is secured asat 62 to the extending end of the slide arm 35 and has its opposite endslidably inserted in the guide end 58 of the saw arm. A pair of guidearms or brackets 64 and. 66 depend from the saw arm 52 in a convergingangle of inclination and are slotted at their lower ends to slidablyaccommodate the straight edge of the saw blade.

A vertically extending handle 68 and a horizontally disposed handle 10are provided to enable an operator to, adjust the machine vertically andhorizontally. A conventional switch 12 controls the operation of themotor and is mounted on the rear portion of the motor support or mount20. A suspension eye 14 vertically extends from the motor mounting shelf20 and a swivel nut 16 disposed at one end of a cable or similarflexible carrying member 18 is detachably associated with the eye, asseen in Figure 2, the opposite end of the cable 18 beingcounter-weighted and passing over a pulley on the carcass carryingtrolley, in accordance with conventional practice.

In operation, the operator may easily guide the machine through thecarcass, employing the handle 68 and 10, the saw arm and blade structurebeing inclined forwardly and downwardly, so that the operator merely hasto guide the saw to form the longitudinal division in the carcass fromthe rump downwardly. When the motor is actuated, through the medium ofthe switch, the pitman or crankshaft, eccentrically attached at itsinner end to the flywheel, will impart a reciprocatory movement in thesaw blade 60, guided in its movement by the guide arm and guidebrackets. of course, the operator can easily raise or lower the saw orturn the saw at any lateral angle or at any inclined position, accordingto the nature of the work, by means of the operating handle and theswivel connection in a manner of attachment.

It is to be particularly noted that the saw-arm assembly 50 is arcuatelyconfigured and so contoured or streamlined so that there are no squarecorners. Thus, the saw is much more convenient and efficient inoperation since vibration of the saw is greatly eliminated and movementof the saw assembly through the carcass is easier and faster. Also, thesaw assembly is easier to keep clean.

Since other uses and embodiments of the instant invention are possible,it is to be understood that changes in the design, arrangement of partsand the like structural transformation may be carried out, the samecoming within the spirit and scope of the appended claims.

Having described the invention, what claimed as new is:

1. A carcass splitter comprising an elliptical housing, a back wallsecured on said housing, a front cover detachably secured on saidhousing, a laterally extending shelf secured on the top of said housing,a motor mounted on said shelf adjacent one end of said housing, saidback having an opening therein, a shaft of said motor exmounted on saidback wall at the opposite end from said flywheel, said guide includingparallel guide rails, a slide arm mounted in said guide rails, a pitmanconnecting said eccentric pin to said slide arm, a saw arm attached tosaid housing, a saw slidably mounted on said saw arm, a drivingconnection between said slide arm and said saw.

2. A carcass splitter comprising an elliptical housing, a back wallsecured on said housing, a front cover detachably secured on saidhousing, a laterally extending shelf secured on the top of said housing,a motor mounted on said shelf adjacent one end of said housing, saidback having an opening therein, a shaft of said motor extending throughsaid opening, a flywheel keyed on said shaft in said housing, aneccentric pin mounted on said flywheel and extending laterallytherefrom, a longitudinally extending guide mounted on said back wall atthe opposite end from said flywheel, said guide including parallel guiderails, a slide arm mounted in said guide rails, a pitman connecting saideccentric pin to said slide arm, a saw arm attached to said housing, asaw slidably mounted on said saw arm, a driving connection between saidslide arm and said saw, a downwardly disposed angular extension on saidshelf disposed in front of said motor in shielding relation between saidmotor and said saw.

3.
